Grain-size characteristics of the extant tidal flat sediments along the Jiangsu coast, China

Five types of sediments have been identified for the tidal flat deposits along the Jiangsu coast: (1) fine sand, (2) sandy silt, (3) silt, (4) clayey silt, and (5) clay. Among these, the silt deposits (including sandy silt, silt and clayey silt), with median grain diameter of 4–7Φ are the dominant sediments within this particular intertidal environment; they normally have good sorting, and are symmetrical or positively skewed and single and/or...
